Answer

To round off the number 4621 to 2 significant digits, follow these steps:

### Step-by-Step Solution:

1. **Identify the Significant Digits**:
The number 4621 has four significant digits: 4, 6, 2, and 1.

2. **Determine the First Two Significant Digits**:
The first two significant digits in 4621 are 4 and 6.

3. **Look at the Next Digit**:
The next digit after the first two significant digits (4 and 6) is 2.

4. **Apply Rounding Rules**:
According to rounding rules, if the next digit (2) is less than 5, we do not increase the last significant digit (6 in this case). Therefore, we keep it as is.

5. **Write the Rounded Number**:
Since we are rounding to 2 significant digits, we write the number as 46.

6. **Adjust for Place Value**:
Since 46 is in the thousands place (4621), we express it in the appropriate place value, which gives us 4600.

### Final Answer:
After rounding off the number 4621 to 2 significant digits, the value becomes **4600**.
